![]() In our case we used NGINX to redirect the access to Kibana (Elasticsearch Dashboard Tool) and PgAdmin4 (PostgreSQL Admin Tool) so that we can access both services on the same port (80) in the browser with different base paths: and docker-compose.yml: version: '3. To have one access port (port 80 or 443) you can use a reverse proxy. In our next lesson, we will flex our SQL muscle □ by loading the taxi zones lookup table and reviewing JOIN and GROUP BY operations.If you have multiple services running on Docker with different ports, you have to open ports in your firewall and you have to access the services via different ports in the browser. Ran Postgres and pgAdmin containers with Docker Compose.Since we didn't start it with this option, we must exit the process with ctrl+c and then stop the containers with docker-compose down So the terminal doesn't get locked by the running process. Typically, we will start docker-compose in detached mode with docker-compose up -d If you need a refresher on how to do this, we wrote the details in our week 1 lesson 3 post. Now we can check if the data is still there by using pgAdmin's query tool. Fill in the hostname, username, and password.Īfter completing the server configuration, MB1 on the Save button. To get to the server configuration screen, MB1 on the Server tab on pgAdmin left pane, then MB2 over it, and follow Create > Server. We can now go to a web browser and refresh the pgAdmin tab ( localhost:8080), log in with the credentials specified in the docker-compose.yaml file and configure the server again, as shown below. Pgadmin_1 | Booting worker with pid: 80 Running Docker Compose. Pgdatabase_1 | 11:34:47.095 UTC LOG: database system is ready to accept connections Pgdatabase_1 | 11:34:47.048 UTC LOG: database system was shut down at 11:34:40 UTC Pgdatabase_1 | 11:34:46.939 UTC LOG: listening on Unix socket "/var/run/postgresql/.s.PGSQL.5432" However, if you wish to install pgAdmin 4 then you would need to enable the PostgreSQL Global Development Group (PGDG) APT repository that contains the PostgreSQL packages for Debian and Ubuntu. ![]() By default, Debian 10 ships with pgAdmin 3. Pgdatabase_1 | 11:34:46.879 UTC LOG: listening on IPv6 address "::", port 5432 Now let’s take a look at how our Support Engineers install the PgAdmin in Debian. Pgdatabase_1 | PostgreSQL Database directory appears to contain a database Skipping initialization Running PGAdmin with Docker-Compose We can achieve the same functionality with docker-compose. doneĪttaching to 2_docker_sql_pgdatabase_1, 2_docker_sql_pgadmin_1 To access PGAdmin, open your favourite browser and head over to then login with the username and password set up in environment variables. Which will run the containers specified in the docker-compose.yaml file. To run Docker Compose, go to a terminal window and change directories until you reach our working directory (the one with the docker-compose.yaml file), and then type docker-compose up docker psĬONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES The empty table returned after stopping containers. We can check if the containers are running with the docker ps command. □♀️ Running Docker Composeįirst, we must stop the containers we started in our last post (Postgres and pgAdmin) by going to their respective locked terminal window and typing ctrl+c. Also, since we defined both services here, they automatically become part of the same network. When we run Docker Compose using this file, we will be able to access the database with the service name specified here ( pgdatabase) from pgAdmin. ![]() "./ny_taxi_postgres_data:/var/lib/postgresql/data:rw" Now, create a docker-compose.yaml file in our project working directory, following a similar structure as in the example from the docs, and fill it with our containers' configurations. Let's peek into the Getting started Docker Compose guide to see the typical file components. First, we download and install it with sudo curl -L "$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-composeĪnd then, we add executable permissions to the binary with sudo chmod +x /usr/local/bin/docker-compose ✏️ Create a Docker Compose file We will follow the Linux systems installation instructions in the Docker docs to install Docker Compose. ![]()
